ABSTRACT:
Two sail structures are disclosed for use in propelling a movable body, such as a ski, skate, iceboat or the like, over a solid surface. One sail structure uses the lateen configuration and includes a triangular shaped sail with an upper spar and lower boom for holding the sail in an open, triangular form; as well as a mast, connectable to the spar and boom, for supporting the sail in a lateen configuration. The other sail structure includes a vertical mast and a horizontal boom connected in a "cross. " A first right-triangular sail is connected at its three corners to the forward end of the boom, the top of the mast and the coupling point of the mast and boom. A second right-triangular sail has its edges connected along the mast and boom, between the coupling point and the top of the mast and between the coupling point and the rearwad end of the boom. With both sail structures, the bottom of the mast is detachably coupled to the transport body in such a manner that the mast may be articulated with respect to the body in any direction.
